PNEUMATIC HORSE-COLLAR.

v SPEGIFIGATION forming part of Letters Iatent No. 791,788, dated June6, 1905.

Application filed April 28, 1902. Serial No. 105,042.

To all whom it may concern:

Be it known that I, CLARENCE T. HOWARD, acitizen of the United States,residing in Rosedale, in the county of Wyandotte and State of Kansas,have invented a new and useful Improvement in Pneumatic Horse-Collars,of which the following is a specification, reference being had thereinto the accompanying drawings, forming a part thereof.

My invention relates to improvements in pneumatic horse-collars. The obect of my invention. is to provide a horse-collar that maybe inflatedsimilarly to a bicycle-tire.

" My invention provides, further, means. by which the horse-collar maybe retained in shape when inflated irrespective of the load that maybebrought to bear upon it.

My invention has for its further object the providing of a resilient bowwhich is placed in the outer Wale or roll casing for firmly retainingthe inflated collar in shape.

My invention provides certain other novel features of constructionhereinafter fully described in the claims. 1

In theaccompanying drawings, which illustrate my invention, Figure. 1 isa front elevation view of aresilientbow. Fig. 2is avertical sectionalview of the inflatable portion of the collar. Fig. 3 is afront'elevation viewiof the collar. the dotted line a b of Fig. 3.

Similar characters of reference indicate similar parts. i

1 indicates the hollow body of the horsecollar, made, preferably, ofleather and of the ordinary shape, but provided with open ends for theinsertion of an inflatable tube 2, constructed, preferably, of rubberand having closed ends. The tube 2 may be similar in construction to anordinary inner tube of a bicycle-tire. An inflating-Valve 3, constructed similarly to valves used for this purpose, is secured at its innerend to the interior of the tube 2 and extends through the wall 1 of thebody of the collar to the exterior thereof. This valve 3 is preferablylocated in the lower end of the collar, as shown in Figs. 2 and 3. Theopen ends of the body of the collar are Fig. 4 is a cross-section takenon end-of the collar and thebuckle 7 connected,

by means of a strap .8, to the other buckle 5.

The body of the collar on its front side is shaped to form the casing ofthe outer wale or roll 9, which is of the ordinary shape. Within thecasing of the roll 9 when the collar is constructed is placed a bow 10,which is sufliciehtly resilient to enable the collarbeing opened at itsupper end, so that the collarmay he slipped upon a horses neck, butwhich is sufliciently rigid to retain the body of the collar in propershape when pressure is placed uponit in the drawing of a load. I preferto make the bow 10 of some tough wood, such as hickory; but it may bemade-of other materials, such as a tube of steel, which will possessconsiderable rigidityv and will yet yield sufliciently for the purposeof opening the collar. In constructing the collar, the leather formingthe body 1 and the roll 9 is preferably formed closely around the bow 10and sewed'where theroll joins the body at 11. The two free edges of thecollar may then be sewed together in the usual manner, thus forming thehollow body. The flaps '4 are for the purpose of closing the ends .ofthe collar, so as to permit the insertion and Withdrawal of the innertube and also to prevent its working out at the ends.

. In operating my invention, the parts having been assembled as alreadydescribed, the tube Q'isinflated with air through the valve 3, afterwhich the ends are closed by securing the straps 4 to their respectivebuckles 5. The

collar may then be applied to a horses neck in the usual manner.

In drawing a load pressure of the hames upon the body of the collar whenthe roll-casand wear, a filling of hair, straw, or other substancecomposed of small particles will work through the openings made by thewearing of the surface and the collar will soon be unsupported at all bythe roll, owing to the loss of the portions of the filling. With acollar having the stiff bow of a single piece the wearing through oflarge holes in the rollcasing will not prevent the collar retaining itsshape. The time of service of collar provided. with my invention is thusgreater than with collars in which the roll is filled with sawdust,hair, or straw.

Various-modifications of my invention may be made without departing fromits spirit.

Having thus described my invention, what I claim, and: desire to secureby LettersPatcut, is

1. Ahorse-collar comprising a hollow body,

providedwith open ends, releasable means for securing to each other thesaid ends, twoflaps secured respectively to'and adapted: to cover thesaid open ends, an inflatable tube located in the said hollow body, and:means by which the said tube may beinflated,.substantially as described.

2. Ahorse-col'lar comprisinga hollow body, provided with open ends,two-flaps secured respectively toand adapted to cover-said open ends, aninflatable tube located in; the said hollow body, and aslightly-resilient bow secured to the said body, substantially asdescribed.

3. A horse-collar comprising ah'oll'ow. body provided with open ends,two flapszsecured: respectively to and adapted to cover the said openends, an inflatable tube located in the said hollow body, a hollow rollor Wale connected with the inflatable-body, and aslightlyresilient bowdisposed in the said roll: or wale, substantially as described.

4. In a horse-collar, the combination with As the roll becomes wornthrough due to abrasion.

a hollow body, of releasable means for securing to each other the endsof said body, two flaps secured respectively to the ends of the body andadapted to close the said ends, an inflatable tube located in saidhollow body and means for securing the free ends of the said flaps whenin the closed .position,,substantially as; described,

5. In a horse-collar, the combination with a hollow body provided withopen ends, of

a an inflatable tube located in said hollow body,

two flaps secured respectively one at each end to the said hollow bodyand adapted to be swung to cover said open ends, means for securing thefree ends of the said flaps when in the closed position, a hollow rollconnected with the said body, and a slightly-resilient bow disposed in.the-said hollow roll, substantially as described- 6. Isn-ahorse-collar,the combination with a hollow body provided with open: ends, of aninflatable tube located; in said hollow body, two flaps securedone toeach. end of the body and adapted to be swung to cover said open ends,two bucklessecured one to each end: oi the body and adapted respectivelyto" engage the said flaps, two straps-secured one to each of saidbuckles, and abuckle mounted on one of said strapsand: adapted to beengaged by the other strap, substantially as described.
